Patent CA-2484799-C (CA)
Title: Device and method for regenerating an electroless metal plating bath
Inventor: HEYDECKE JENS
IPC: C23C18/31
Filed: 2003-08-14
Granted: 2012-10-16
Abstract: In regenerating an electroless metal plating bath by electrodialysis, it has been found that the metal of the metal plating bath deposits in the electrolysis arrangement. To overcome this problem, an improvement to prior art regenerating devices is suggested, said improvement consisting in providing main cation exchangers for removing ions of this metal from a concentrate fluid. The main cation exchangers are coupled to the concentrate compartments of the electrolysis arrangement in such a manner that the concentrate fluid flowing through the concentrate compartments is allowed to pass through the main cation exchangers and to be recirculated back into the concentrate compartments.

Abstract: L'invention concerne un appareil et un procédé pour détecter l'emplacement d'une fuite de gaz dans une zone d'essai. L'invention comprend un réseau de capteurs étalonnés pour mesurer une pluralité de concentrations de gaz ; un système de commande couplé au réseau de capteurs pour calculer et éventuellement afficher une direction dans laquelle la concentration de gaz est supérieure ; et un actionneur pour déplacer le réseau de capteurs au moyen du système de commande. Le système de commande fait en sorte que le réseau de capteurs mesure des concentrations de gaz et se déplace en direction d'une concentration supérieure de gaz jusqu'à ce qu'une condition d'arrêt soit remplie. La condition d'arrêt peut être remplie lorsque la concentration de gaz mesurée dépasse un seuil prédéterminé, ou lorsque la concentration correspond, sur la base d'une comparaison avec des valeurs mesurées précédemment, à l'emplacement de la fuite.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

Abstract: A method for cleaning and/or altering an inside surface and shape of a tubular is disclosed. The method includes placing a surface finishing tool in the tubular, energizing the surface finishing tool, and causing extendable assemblies therein to extend radially to contact an inside diameter of the tubular. Moving the surface finishing tool axially and/or rotationally while the extended members are in contact with the inside diameter of the tubular cleans debris from the inside surface of the tubular. In another aspect of the invention, the tool burnishes the inside diameter of the tubular, thereby altering the surface characteristics and rounding the tubular.

Title: Retractable shower expander assembly
Inventor: BATHURST DAVID
IPC: A47K3/38
Filed: 2005-09-22
Granted: 2008-06-17
Abstract: A retractable shower expander assembly for a shower stall or tub enclosure having an access opening includes a shower expander rod, two expander ports and a tension rod. The shower expander rod is formed with right angles on each end and is selectively adjustable in the middle to fit various access opening widths. The retractable shower expander assembly, being portable, is held in place by means of an adjustable tension rod, that, when enjoined inside the cavities of the two expander ports, holds the retractable shower expander assembly horizontally and fixedly in use against the two end walls of a shower stall or tub enclosure at the top of the access opening. A  shower curtain is attached to the shower expander rod by hooks or rings that can slide along the shower expander rod to selectively close or open the access opening of a shower stall or tub enclosure. When outwardly force is applied to the shower expander rod the two right-angle ends extend or telescope through the apertures in the center of the expander ports and move the shower expander rod with the attached shower curtain outwardly away from the access opening to provide the maximum amount of increased area inside the shower stall or tub enclosure. When inwardly force is applied to the shower expander rod the opposite retracting or telescoping effect moves the shower curtain toward the access opening and returns it to a straight hanging position within the shower stall or tub enclosure access opening to be more aesthetically pleasing and conserve space in the bathroom.

Abstract: A simplified scrambling scheme that unifies all signals of a satellite broadcasting system, including frame header (404), frame body (402) and pilot symbols (408) with a common reference phase. This results in the simplification and increased flexibility of the receiver front-end design without affecting the overall system performance. In many current communications systems with frame headers and pilot symbols, the phases of frame headers and pilot syrnbols are not designed to be aligned with any constellation points of the modulated data from the frame body. This scrambling scheme takes into account possible impact due to irregular phase changes between frame headers/pilot symbols and modulated data.

Title: Solver for a restrained deformable system with released degrees of freedom
Inventor: DE HILLERIN CHARLES-ANDRE
IPC: G06F17/50
Filed: 2006-04-05
Granted: 2014-09-09
Abstract: For determining the behaviour of a system submitted to predetermined load and displacement boundary conditions with a degree of freedom relative to a local coordinate system released at one node of the system, a process uses finite element analysis. For a geometrically non-linear solution scheme, the process has a plurality of incremental steps. In each incremental step, one computes for a finite element of the system a displacement vector at the nodes of the finite element. This computation of the displacement vector is carried out by minimising the energy of the system when the system is submitted to the predetermined load and to a fraction of the predetermined displacement. For a geometrically linear solution scheme, the process is carried out in a single solving step. In this step one computes for a finite element of the system a displacement vector at the nodes of the finite element. The computation is carried out by minimising the energy of the system when the system is submitted to the predetermined load and to the predetermined displacement. The step of minimising is carried out, for a node having a released degree of freedom, in a local frame of reference. The released degree of freedom at the node is expressed along one axis of the local frame of reference. Using such hydrid reference frames makes it possible to express and to take into account in the global formulation the constraints for the non-released degrees of freedoms in a simple manner, without having to factorise constraints;
